Meet Ananya Nagendra, 18, who built an ant-based digester for food waste
A student developed an ant-based digester to process food waste efficiently. This innovative system uses ants to break down organic materials, reducing landfill methane. Experiments showed Camponotus castaneus ants consumed the most waste, proving effective. Her prototype achieved an impressive eighty-three percent efficiency in initial tests. This research offers a novel biological approach to…
Food waste typically ends up in landfills, where it decomposes and produces methane, a potent greenhouse gas. This problem prompted 18-year-old Ananya Gulur Nagendra, a student from Plano, Texas, to investigate if ants could help tackle food waste. As a finalist in the 2026 Regeneron Science Talent Search, Nagendra studied how ants could break down food waste and created a prototype of an ant-based aerobic digester.
Her experiments involved testing four ant species to determine their efficiency at consuming waste. Camponotus castaneus emerged as the most effective species, performing the best and having the highest metabolic rate. Based on these findings, Nagendra designed a system that could potentially reduce methane emissions by up to 83%.
While the prototype is still in the early stages, it demonstrates how biological processes can inspire innovative waste-management solutions.
